Description
Technical Field
[0001] This utility model relates to the field of roadbed slope protection technology, specifically to a roadbed slope protection device. Background Technology
[0002] In daily travel, highways can bring great convenience to pedestrians. Due to the terrain, the roadbed of some highways is often higher than the ground, which creates a slope between the highway and the ground. After long-term exposure to sun and rain, the soil of the roadbed slope will become loose, which may lead to landslides. This will not only damage the roadbed, but also cause great safety hazards.
[0003] Roadbed slope protection devices can be installed on the slopes to protect the roadbed slopes. Common protection structures include grids, arches, or reinforcement plates installed on the slopes using anchor bolts. However, these protection structures are all installed on the surface of the roadbed slope. When used on roadbed slopes with high soil moisture and loose soil, conventional fixing structures such as anchor bolts cannot fully guarantee the installation stability of the grids or reinforcement plates. When the roadbed slope becomes loose or soil and water are lost, the protection structure is prone to losing its function.
[0004] Therefore, in response to the above problems, a roadbed slope protection device is proposed to solve them. Utility Model Content
